Conclusions
-
1.
The presence of evenly distributed retained austenite in amounts not over 30% in high-strength maraging steels leads to an increase of the ductility with retention of fairly high strength.
-
2.
It is expedient to use rapid heating for heat treatment of MS in order to prevent decomposition of martensite and redistribution of the components in the biphase (α+γ) region.
